I have 3 cameras with HDMI output that are connected to my vMix computer with a capture device. Each of the 3 capture devices are different and a link below is similar to the devices I am using. I need to add a fourth camera but need to know if anybody has any experience with these to know how many of these things I can connect to my computer. I am using a powered USB 3.0 hub so I can connect them all. Capture Device

USB3 controller port offers 5 Gbits bandwidth
a single 1080 feed is 1.5 Gbits
Do the math ! ;)
Go for PCI-Express capture card or Thunderbolt3

Looks like I will have to spring for a PCI capture card. Do any of the ones listed below have advantages over the others?
Magewell P/N 11100 $899
Avermedia P/N CE314-HN $899
Blackmagic Decklink Quad $545
Chinese model on Ebay $475
The one on Ebay is obviously the cheapest, but is shipped from China and has no returns. Not touching that one. The Blackmagic
has a fairly low price compared to the others. Can I assume it works well also?
